Installation Guidelines

Please follow these guidelines for setting up the Switch:

• Install the Switch on a sturdy, level surface that can support at least 6.6 lb. (3 kg) of weight. Do not place heavy objects on the Switch.

• The power outlet should be within 1.82 meters (6 feet) of the Switch.

• Visually inspect the power cord and see that it is fully secured to the AC power port.

• Make sure that there is proper heat dissipation from the Switch and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation.

• Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges.

• Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.

• When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet cushion the Switch, protect the casing from scratches, and prevent it from scratching other surfaces.

Installing the Switch without the Rack

First, attach the rubber feet included with the Switch if installing on a desktop or shelf. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the Switch and any other objects in the vicinity.

Installing the Switch in a Rack

The Switch can be mounted in a standard 19″ rack. Use the following diagrams as a guide.

Fasten the mounting brackets to the Switch using the screws provided.

Powering On the Switch

Plug one end of the AC power cord into the power connector of the Switch and the other end into the local power source outlet.

After powering on the Switch, the LED indicators will momentarily blink. This blinking of the LED indicators represents a reset of the system.

Power Failure

As a precaution, in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in.

Installing the SFP ports

The D-Link DWS-3000 series switches are equipped with SFP (Small Form-factor Pluggable) ports,which are to be used with fiber-optical transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances. These SFP ports support full-duplex transmissions, have auto-negotiation and can be used with DEM-310GT (1000BASE-LX), DEM-311GT (1000BASE-SX), DEM-314GT (1000BASE-LH) and DEM-315GT (1000BASE-ZX) transceivers. See the figure below for installing the SFP ports in the Switch.

The rear panel of the D-Link DWS-3026 includes two open slots that may be equipped with the DEM-410X 1-port 10GE XFP uplink module, or a DEM-410CX 1-port 10GBASE-CX4 uplink module, both sold separately.

Adding the DEM-410X optional module allows the switch to transmit data at a rate of ten gigabits per second. The module port(s) are compliant with standard IEEE 802.3ae, support full-duplex transmissions only and must be used with XFP MSA-compliant transceivers.

The DEM-410CX uses copper wire medium, not optic fiber and therefore has a transmit length limit up to 1 meters. Compliant with the IEEE802.3ak standard, this module uses a 4-lane copper connector for data transfer in full-duplex mode.

To install these modules in the D-Link DWS-3026 Switch, follow the steps listed in this section.

CAUTION: Before adding the optional module, make sure to disconnect all power sources connected to the Switch. Failure to do so may result in an electrical shock, which may cause damage, not only to the individual but to the Switch as well.

At the back of the Switch to the left are the two slots for the optional modules. These slots must be covered with the faceplate if the slots are not being used. To install a module in an available slot, remove the faceplate by loosening the screws and pulling off the plate.

Unplug the Switch before removing the faceplate covering the empty slot. To install the module, slide it in to the available slot at the rear of the Switch until it reaches the back, as shown in the following figure. Gently, but firmly push in on the module to secure it to the Switch. The module should fit snugly into the corresponding receptors.

Now tighten the two screws at adjacent ends of the module into the available screw holes on the Switch. The upgraded Switch is now ready for use.

Connecting to the External Redundant Power System

The Switch supports an external redundant power system (RPS). The diagrams below illustrate a proper RPS power connection to the Switch. Please consult the documentation for information on power cabling and connectors and setup procedure.
